Handwashing Laboratory Activities: Bowl Technique
Source Institutions
In this lab (Activity #2 on page), learners compare bacteria growth on two petri dishes containing nutrient agar. Learners touch the doors, faucets, etc.
Plant Tissue Culture: Classroom Activities in Plant Biotechnology
Source Institutions
In this activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet le
Ruminating on the Digestive System
Source Institutions
In this activity, learners will review the functions of basic digestive organs, understand how diet affects digestion, understand how digestive tracks may differ, and then step outside to compare the
Does Sunscreen Protect My DNA?
Source Institutions
In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.
Rock Pioneers
Source Institutions
In this outdoor activity/field trip, learners investigate organisms that live along the ocean's rocky coast.
Dark Adaptation
Source Institutions
In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.
The Scoop on Scallops
Source Institutions
In this data analysis activity, learners quantify the abundance and distribution of sea scallops in and adjacent to the Mid-Atlantic closed areas.
Crunch Time
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.
Fish Features and Habitats
Source Institutions
In this activity, learners observe live fish in tanks to consider how their body structures are related to their behaviors and habitats.
Catch & Release II: It's Catching On!
Source Institutions
Throw that fish back? A new generation of ethical anglers concerned about conserving resources is participating in "catch and release" fishing. How is this going?
Sea State: Forecast Conditions at Sea
Source Institutions
In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.
Extinct!: Are You Smarter than a Plant?
Source Institutions
In this online activity, learners find out whether they are smart enough to survive as a plant.
DNA the Easy Way
Source Institutions
This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.
Healthy Habitats Have Native Plants
Source Institutions
In this activity, learners help identify native and non-native plant species, learn about invasive species, and determine how native plants provide a healthier habitat.
Mapping Mockingbirds
Source Institutions
This lesson plan revolves around studying the speciation of the Galápagos mockingbirds, which are on display at the California Academy of Sciences.
Desert Water Keepers
Source Institutions
In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.
First Impressions
Source Institutions
Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.
Measuring Biodiversity
Source Institutions
Learners use a variety of beans to represent a variety of species, and scatter these beans over a large piece of paper representing the environment.
Envirolopes
Source Institutions
In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.
Observing Insects at Night
Source Institutions
In this activity, learners set up a night time insect observation station with a light and sheet.
